Final answer:
Complications with the pudendal block can include localized hematoma, infection, nerve injury, difficulty with urination, and in rare cases, confusion or delirium.
Step-by-step explanation:
A pudendal block is an anesthetic technique used particularly during labor to relieve pain. While it is generally effective in managing pain, complications can sometimes occur with the pudendal block. The most common issues include localized hematoma, infection at the injection site, or nerve injury. Patients may also experience temporary difficulty with urination or a change in bladder control due to the effect of the block on the nerves controlling the micturition reflex. In rare cases, the anesthetic might spread to nearby nerves, affecting other lower body functions and possibly leading to episodes of confusion or delirium.
